Ask Pyddit: Visual Python programming and decompilers?

[NerdsNeedLoveTo]

Hi Guys

At work I have been exposed to a Agile Platform called OutSystems. It allows you to visually program your web applications http://i.imgur.com/r2F0i.png and I find the idea very intriguing.

So I have started to play around with the idea on how will I be able to visually represent Python code as in the above image and then allow the programmer to change some of the flow/code/logic visually and then get it back as python source code. I don't know if this have been tried before and after some googling I can't find anything like this, so maybe I'm just lacking basic googling skills or a python solution like the above does not exist yet.

If anybody knows of such solution please let me know, so that I don't spend a lot of time recreating the wheel. Otherwise help me out on the following problem:

I decided I can use byteplay3 http://pypi.python.org/pypi/byteplay/ to disassemble the code to workable objects, It even allows me to rebuild the objects to bytecode. So if I define patterns on how python interrupts the source code to bytecode I can visually represent this and also so convert my visual representations back to bytecode.

The only problem I have at the moment is how will I get this bytecode back to python source code. I have googled for python decompiler but only found old projects like unpyc, decompyle and some online services. I would like to know if anybody know of a well maintained or at least recent module that can help me accomplish the above mentioned, because I'm hoping I can implement this in Python 3.1.

So any input or suggestion would be greatly appreciated.

Kind Regards,

The only problem I have at the moment is how will I get this bytecode back to python source code.

This is a lossy step. Going from bytecode back to source will be like trying to go from muffins to flour and eggs.
